(Cl. 'l2-17) 1 Claim. 1

This invention relates to a wall structure and method of constructingthe same. It especially relates to wall structures for single familyresidences.

It is Well known that there is a great demand for low cost homes whichdemand is not met by the present type of building construction.Buildings having brick and brick veneer walls have been found to be tooexpensive for the average home owner. Cement block walls are urpsightlyand tend to undesirable uniformity and the present shortage of lumberhas retarded the building of Wood wall homes even where suchconstructions are permitted.

This invention has for its object a wall of sturdy .construction whichcan be easily erected at low cost from materials which are alwaysavailable in the open market.

Another object is the erection of a building Wall structure which ispractically moisture proof which contains insulating elements and isfire resistant. A still further object is the erection of a low costbuilding wall of pleasing appearance which can be either an outside orinside Wall and may be colored to suit the taste of the individual homeowner.

I have found that a strong durable low cost wall construction may bebuilt from wall forming insulating or wall board of any desired typewhich is fastened to the vertical studs in the usual manner to form awall. The insulating board is then coated with a thin coat of anydesired mastic to which is applied a covering of asphalt impregnatedroofing paper having mineral granules embedded in its outer or facingsurface, the said roofing paper completely covering the wall structure.The roofing paper and granules are then covered by a decorative coatedcomposition which may be of any desired type and color.

The foregoing and such other objects of my invention as may hereafterappear are illustrated in the drawing in which Fig. 1 is a face view ofmy new wall structure shown partly in section.

Fig. 2 is a cross section in perspective of a portion of the wallconstruction taken on line 2-2 of Fig. 1.

Referring to the drawings there is shown the vertically disposed woodframe studs I erected in the usual manner to which are attached by anywell known fastening means wall forming insulating board ll. Theinsulating board attached to studs I0 forms an entire wall which iscoated with a coat of mastic l2 and covered with the impregnated roofingpaper I3. Em-

bedded in the outer or facing surface of the roofing paper i3 aremineral granules ill of any general uniform size. The roofing paper I3and the mineral granules lll are covered with the decorative coatingcomposition l5.

I have found that satisfactory results are ob tained by using a Wallboard such as is now being sold cn the market under the trade-markCellotex an asphalt mastic, roofing paper with granules of the generalsize of 10 or 12 inch mesh and a decorative coated composition ofPortland cement. This makes a wall construction of low cost, easy toconstruct, of sturdy character, substantially moisture proof, fireresistant and of pleasing appearance.

While I have particularly described a single wall structure, as shown inFig. 1, I find that the best results are achieved by a. double wallconstruction such as shown in Fig. 2, the outer wall forming the outsidewall of the building and the inner wall forming the inside wall of aroom. The wall structures being identical, I do not believe any detaileddescription of the construction of the second wall is necessary. Theadvantages of the double wall structure are readily apparent to thoseskilled in the art.

While I have shown and described a particular embodiment of myinvention, it will be understood of course that I do not wish to belimited thereto since many modifications may be made which may comewithin the scope of the present invention for which I claim:

In combination, a double wall structure arranged in parallelrelationship on a common plane, a plurality of vertically disposed studscommon to both walls, wall forming insulating board attached to theopposite sides of said studs, a layer of mastic on the outer surfaces ofsaid board, asphalt impregnated roofing paper adhering to said mastic,mineral granules embedded in said roofing paper, said roofing paper andgranules being covered by a coating of Portland cement.
